Specification of Letters Patent.

Application filed August 7.19%. Serial iio. 27s.o14.

To all whom it may concern:

Be it known that 1, JOHN A. STROM, a citizen of the United States, residing at Pullman, county of Cook and State of Illinois, have invented certain new and useful Imrovements in Radiators, of which the folowing is a description.

My invention relates to that class of devices employed to regulate the temperature of a room or other space by the circu ation of a heating or a cooling fluid.

The object of my invention is to provide a device of the kind portions of the system in each room or space as desired may be made activeby the circulating fluidwithoutin any manner interferin with the circulation of the fluid in any ot er portion of the entire system.

' T this end my invention consists in the novel construction, arrangement, and com- ,bination of parts herein shown and described and more particularly pointed out in the claims.

In the accompanying drawings wherein like or similar reference characters indicate like or corresponding parts :-Figure 1 is a longitudinal vertical section of a small radiator. Fig. 2 is a similar section of a larger radiator. Fig. 3 is a section taken substantially on line 33 of Fig. 1. Fig. 4 is a section taken substantially on line ll-*4: of Fig. 2. Fig. 5 is a longitudinal vertical section of a wall coil or radiator with a water heater upon the return pipe. Fig. 6 is an elevation o .the preferred arrangement of my radiators in a railway car. Fig. 7 is an elevation of a slightly modif ed form of my device. Fig. 8 is a section taken substantially on line 8-8 of Fig. 5. Fig. 9 is an end elevation of the form shown in Fig. 5. Fig. 10 is a'section taken substantially n line 1010 of Fig. 7.

' Fig. 11 is an elevation of amodified form of my device, an Fig. 12 is an elevation of a systemshowing a modified arrangement of the several parts of my device.

In the form of my device shown in the drawings, each radiator consists of one or more practically independent ed as preferred, each unit in the preferred form consisting of a substantially similar arrangement of pipes viz., a main loop comprising a receiving pipe 1, a discharge pipe 2, a connecting pipe 3, between pipes 1 and 2 which may in some cases be common to several units, and one or more auxiliary loops 4 the preferred described whereby such units connect- 4 each preferably provided with a valve, cook, or other control ing device 5. v

It should be understood that the above terms in so far as they tend to indicate the direction of travel of the fluid through the units are merelyl relative and only indicate rection, as the fluid may travel in the opposite direction with equally as satisfactory results. The auxiliary loops 4 pipes 6 and .7 which may be termed flow and return pipes connected at one end, and at their opposite end connected to adjacent pipes of the unit so that thepipe 6 may be directly opened to the pipe 1 as shown, the connection being controlled by the valve or cock 5 so arranged at the junction of the pipes 1 and 6 that the pipe 1 may be closed forcing all the passing fluidfirst intothe pipe 6, or if preferred, the entrance to the pipe 6 may e closed confining all the passing flui pipe 1. I

In units having only a single auxiliary loop 4 (Figs. 1 and 7) the pipe 7 of the loop 4 also opens directly intothe pipe 1 near the valve 5 so that fluid entering the pipe ing the 100 is again discharged into the pipe 1 be 0nd t e valve5.

ere more ,han one auxiliary loop 4 is rovided, a conduit 8 communicates at one end with the main flow portion of each oop, of one of; the loops bein with the main pipe and t e return portion of each succeeding loop being in communication with the flow portion of the preceding loop, a plurality of valves 5 being provide which are adapted and arranged to permit the return portion in communication the flow of the heatin medium t main pipe only or to irect the flow through one or more of said loops-in succession at wi 1. See Figs. 2-, 5, 11, and 12. It-will be seen that with the valve 5 in the pipe 1 open to the first loop 5" 0 en to the last loop 4", that fluid enter ing t e pipe 1 will flow successively throug the auxiliary loops 4 into the pipe 1 again and that by operating the valves-5, 5 and 5", the loops mag be successively shut ofluntil the fluid ows directly along-thepi 1 radiating surface 0 desired. g 1

The units may be arranged in any desired manner in a eating or cooling system.

6 after pass-- hrough the d to the ipe and also with the and the succeeding valves 5 and- 4 and 4e and thence of vertical units are thus connected andthe pipes Sand 9 connected to the first and last unit of the series.

In Fig. the pipes 1 and 2 are extended at each end 1010 and 1111 for the attach i ment of any desired number of similar units as shown in Figs. 6 and 11 connection 3 in this case being common to. the entire series It should be noted that in this form also as shown in Figs. 6 and 11 the pipes 1 and 2 are continuous, and thus are, like the pipe 3, common to the several units. In this form 'therefore, each auxiliary loop or series of loops may be considered as a unit and the extended main loop as common to them all.

Obviously it is not essential that the pi e 2 should be positioned in the vicinity of the auxiliary loops at all, but may if preferred be placed at the opposite side of a building or upon another floor as shown in Fig. 12 and may have another series of auxiliary loops attached thereto if foundconvenient.

The main loop of each unit may be considered as merely a portion of the main conducting pipe of the system formed to suit the particular conditions under which the system is to be operated.

In the'form shown in Fig.6 a series of horizontal units are shown in a railway coach or sleeping car. By this arrangement the passengers of the section can control the temperature of that particular section to suit themselves without interfering in any manner with the passengers in the adjoining section and if desired the o crating handle 12 of the valve 5 may b 5Q that the porter or other attendant may operate the same without disturbing the occupants of the section.

In the form shown in Fig. 5 an additional pipe or chamber 14 is shown'lying parallel w1th and in contact with pi e 2, obviously if the chamber 14' befilled with water it will tend to attain the temperature of the fluid passing in the pipe 2. Thus when theunits form part of a heating system the heating fluid in returning after passin through the radiators may be employed for eatin water.

In the form shown in Figs. 1, 2, an 5, and their sections, each iinit is formed of one or more castings, while in the remaining figures the entire system'is composed of pipes connected by suitable fittings.

In Fig. 7 the connections at the ends of the auxiliary-loop 4 are formed by suitably unitin an ordinary three way cook or valve and suitable pipe f ttings as ordinarily constructs of a receiving portionl, a discharge portion ed. In Figs. 6, 11, and 12, however the connections between the several auxiliary loops and the main loop is, formed by employing a fitting 15 especially constructed for this pur ose and provided with the necessary 000 s 5, and means for attaching the same to the members of the main loop and the several auxiliary loops as shown.

The operation of my device is believed to be fully set forth in the fore oing description 7 and further explanation is eemed unheces sary.

In the foregoing s ecification only the'preferred form of my evice is shown and de* scribed and it is obvious that various im-. 3

material modifications may be made in my 'device without departing from thespirit of ,my invention, hence I do not wish to be understood as limiting myself to the exact form and construction shown.

What I claim as new, and desire to secure by Letters Patent is: 1'. In a radiating device, a single piece structure comprisinga main loop consisting 2, .the communicatmg conduit 3, of an auxiliary loop consisting of a flow portion 6 and return portion 7 the flow and return portions being in communication at one of their ends, and being offset at their opposite ends, the off set art of the flow portion communicat: ing wit the receivin I ipe of the main loop, and the ofi set part 0 t e return portion also communicating with the receiving ipe of the main loop, and a valve 5 in the em receiving pipe adapted and arrangedto ermit the flow of the heating medium throug the main loo only or to, direct the flow through the a iary loop and then throu h the main loop.

2; In an apparatus 0 the character described, the combination of a main loop comprising a receiving pipe a discharge pipe, and a connecting pi e, of an auxiliary loop arranged within t e main loop comprising a flow portion and a return portion, a conduit communicating at one end with the receiving pipe of said main loop, and also communicat- 1ng with the fiow portion of the auxiliary loop the return portion of the auxiliary loop being in communication with the main pipe, and a valve. arranged and adapted to ermit the flow of the heatin medium throug the main loop only, or to irect the flowthrough the auxiliary loop and thence through themain 3. In an apparatus of the character 'described, oppositely disposed flow and return pipes connected to oneanother at one of" their endsto form an auxiliaryloop, the other end of the returnplipeb'ein' offset and open- 1 ing directly into t e main oop including an elongated pipe extending parallel to the pipe of the auxiliary loop, the said main loop, and the free end of the flow pipe communicating witha transversely arranged conduit in com- 1 5 throu munication with the main loop, and controlling means in the'main loop arranged and adapted to permit the heating medium to flow directly through the main loop only, or
